Returns the content of a specific best practice skill
AI agents call get_skill to retrieve information from Personal Code Skills MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries stored markdown files containing coding guidelines from a GitHub repository. It performs a simple data retrieval operation without creating, modifying, deleting, executing code, or triggering external operations. The only risk is potential exposure of internal coding standards if the repository contents are sensitive, but the tool itself is read-only and low-risk.
From the tool's definition Tool description states it 'Returns the content of a specific best practice skill' — a retrieval operation with no modifications, deletions, or side effects. Sibling tools 'get_skills' and 'list_skills' further confirm a read-only pattern.
Attacks that exploit this kind of access
Returns the content of a specific best practice skill. It is categorised as a Read tool in the Personal Code Skills MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Personal Code Skills MCP Server MCP server in PolicyLayer and add a rule for get_skill: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Personal Code Skills MCP Server. Nothing to install.
get_skill is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_skill rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_skill. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_skill is provided by the Personal Code Skills MCP Server MCP server (lfdantoni/my-personal-code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
